is the average weather condition of an area over a long period of time
Answer:
Both parents are heterozygous for the trait. They must be carriers of the recessive gene that codes for blue eyes.
Explanation:
Let us assume that the dominant gene codes for brown eyes while the recessive gene codes for blue eyes. We can suggest that both parents are carriers of the recessive gene. They both express brown eyes because they also have a dominant gene that codes for brown. Clark inherited one recessive allele from each parent, so he expresses blue eyes. The couple has a 75% probability of getting a brown-eyed child, while the probability of getting a blue-eyed child is 25%.
When two solutions are separated by the membrane through which water can pass but starch cannot, the osmosis will occur.
Osmosis is described as the spontaneous movement of water through membrane from a region of lower solute concentration into a region of higher solute concentration. Water movement tends to equalize the solute concentrations on the two sides.
